The punches are guided with respect to the die plate by means of a guide plate and stripper A pressure bar l is carriedby 'armsm pivoted on the frame, and a bar 0 having an upturned extension @the upper"- end of which is faced with leather',y extends lbetween the arms m at a ypoint above the punches.' A jseries of selectors g having 'hooked tails rare rotatably mounted on a ishaftls extending between arms m, the se! lectors being so proportioned that theirylupf per ends will normallyfreston the leather 'faced edge `ofthe extension pythe leather 'facing acting as a bumper. An individual 'selector is provided for 'each ofthe black and white ,keys of the 'piano keyboard illustrated on the scale plate, lfor the* sustaining pedal and for any automatic control devices. Thel selectors areprovided with extensions n 8O permitting 'their manual movementV into" andzout of operative position, the extensions of those selectors corresponding to the black keys and those `corresponding `to Ithe white keys of the'piano keyboard being ofdiiier- 'ent rlengths respectively, whereby they ,arey y differentiated. The extensions are provided on theirw upper surfaces with projections 31,

which serve as grips for the fingers when.

f the selectors are' manipulated.` A punch Lis f provided beneath each selector. The punches are adagtedito be operated by the pressure bar Z through bar 0,l operative connection being formed between the punch heads and bar o bythe' tails ron the selectors, which when the selectors are pulled out"y vengage under bar o andform gags, as shown in dotted lines in Figure 3. The retractor bar it is depressed by engagement of bar o with lugs n. It will thus be seen that if any selector or series 'of selectors 'arepulledl out andthe pressure bary depressed, thepunches beneath the'selector pulled willbe operated. On'r the release of the pressure bar, the punches are returned4 to 'normal bythe `re- .tractor bar under'the influence'y ofitssprings.

i spring-tensioned A pan is positioned beneath the punch to collect the punchings. lThe paper vholding and feeding mech anism comprises a blank paper roller t carried by the frame at a point behind the punches and a take-up roller u carried by the frame in front of the punchesto receive the perforated paper. `The paper is led from the roller t under the punches between the guide plate la and the die platee, thence over a feed roller c, mounted on a 'shaft w, one end of which is provided with a turn button m, to the take-up roller u, which `is providedwith a hook, seated in a recess, to receive the end of the paper. The paper is guided to the feed roller by strips 19 and by anges on the rtake-up roller u. Tension is maintainedv on the paper by means of a series of rollers y, carried by levers e journaled on a shaft 2 and tensioned by springs 3 which press on the paper as. it passes over the roller c, The rollers may be lifted from the `roller e by turning shaft 1G which is provided with flat surfacesas indicated in Fig.

The shaft w is provided at one end with a pulley 4 adapted to be driven by a ratchet wheel 5 mounted on the other end of shaft w, through a belt 6 and a pulley '.7 frictionally secured to takeup roller u by a split sleeve 27.

The ratchet wheel is driven by a pawl 9 provided with a cam surface 10, pivotcd to an arm 11 pivotally mounted on shaft w. A spring 12 secured to the pawl andto the arm 11 tends to maintain the pawl in engagement with the ratchet teeth.

lThe pawl is pivotally connected to one l end of a link 13, the other end of which is 40.

pivoted to a spring-tensioned arm 14 integral with one of the pressure bar arms m and formi-ng a bell crank therewith, so that the pawl may be actuated by the pressure bar. The arm 14 extends through an aperture in the frame, the faces of which are provided -with rubber bumpers `15. f A stop 28 is positioned adjacent the arm 14,'which may be moved into and out of the path of the arm, so that when desired the movement of the pressure bar Z may be limited to that required to actuate the pawl without actuating such punches as may be operatively connected by their selectors.

A` spring-tensioned lever 17 pivoted at one end on shaft 2 is provided atits free `end with a roller 8` adapted to engage between the teeth of the ratchet Wheely and ment of the pressure bar. asshown in Fig.

3, so that the ratchet wheel may be backed manually if desired.

f A second lever20'is pivoted at one yend to shaft 2 adjacent to lever 17 and extends downward to the cam surface 10 in pawl 9. A roller 21 mounted on its free end is adapted to contact with the cam surface in the active movement of the pawl and force the pawl away from the ratchet.` An adjusting cam having three faces 22, 23 and' 24 is mounted to position lever 2O against the action of a spring to fix the distance the pawl may advance the ratchet wheel before it is released by the action of cam surface 10. The faces 22 and 23 so position the lever as to effect the release of the pawl when the pawl has advanced the ratchet wheel one and two teeth respectively. The face 24 is adapted to so position the lever as to maintain the pawl out of action and a stop 26 is positioned on the lever 20 so that when the lever is positioned by face 24 the` lever 17 and the spacing roller carried thereby will be thrown out of action and the ratchet wheel will be free to be moved a fraction of a tooth, by hand.

le will now describe the oaeration of the machine :to effect the recor of a selection. A roll of blank lpaper corresponding to roller t is inserted and the free end led under the punchesover roller c and secured totlie hook on roller u. The tension rollers z/ are lowered onto the paper. The sheet vmusic to be recorded is studied and the selector corresponding to the piano key which would be struck for the 'lirstnote is pulled down. The adjusting cam is then setto permit the pawl to move the ratchet wheel two teeth, which has the effect of rotating the feed roller c and advancing the `paper a distance corresponding to thel movement of the ratchet wheel. The pressure bar is now 1 depressed and its initial movement causes the paw] to be advanced through the action of arm 14 on link 13, then rotating the ratchet wheel and roller v and advancing the paper.r their the pawl has rotated the l ratchet wheel a distance of two teeth, it is disengaged by cam surface 10. Further depression of. the Vpressure bar causes the punch corresponding to the selector pulled down to be depressed, through the connection formed by the tail of the selector, and they paper is perforated. If, for example, the first note is a quarter note, the pressure bar is depressed sixteen times, the paper advances between each perforation and the i perforations are evenly spaced. At the point where the next note of the selection comes in the selector corresponding to the `piano key which would be struck to play it is`pulled down, and so on. As each note is completed, the selector corresponding to it is raised and as new notes come in, the selectors corresponding to them are pulled down.

' lf nowthe sheet music calls for a runfl A tvltthe first `perforation of the first note :the perforations of the same'noteI instead of he struck, it is `undesirahle'th'atall :thenotes oflthe run is made,the adjusting eamfis the face 23' and ythe pavvlA Will" loe thrown out after rotating the ratchet one tooth.

The 'spacing between notes 1s nos7 half that under ordlnar'y circumstancesfand being 'spaced are rlapped f as indicated f at 25 in Fig, l, Where a'lportion of amusc roll is'shoivn. Thus, the rapid vslurred effect of the notes in" a'run is olotained. The single tooth advancejof the^feed is also used 'when fast timeis desired, although it 'is impractical Where-the Esame lnote is repeated, jas it' is obvious that 'no spacing l would occur between anote and its repetition, `ivith the-result that the repeated note ivouldhe recorded asia part ofthecrlfginal j If nowgthe selection requiresfa chord to of the chordhe begun-"exactly simultaneously vsince if they' are, a: mechanicaleffect f notes at exactly the same time. rloproduce a natural effect, the adjustingi'cam'is turned t so'- that face Qil'will 'position lever y2O so as to prevent the IpaWl lfrom advancing the ratclfiet,` and lever 17 will be displaced by stop 26 to free the ratchet Wheel.
